' REVOLVING SULKY HAY-RAKE.

SPEGIFIGATIbN forming part of Letters Patent No. 648,583, dated May 1,1900. Application filed January19,1900. Serial No. 1,966. (No model.)

To aZZ whom it may concern:

Be it known that I, AMOS R. BLACK, a citizen of the United States,residing at Lamar,

in the county of Prowers and Stateof Colorado,have invented certain newand useful Improvements in Revolving Sulky Hay-Rakes; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

Theobject of my improvements herein is to provide an efficient, durable,convenient, and automatic self-dumping revolving sulky hay-rake,constructed entirely of steel and iron, that will do speedy and cleanwork in raking heavy hay crops, green alfalfa, cane, and cornstalks-asulky hay rake that the driver can operate the dumping mechanism thereofwith his feet, leaving his hands free at all times to guide the horse.

The invention consists of the arrangements, features, and combinationshereinafter described and claimed.

The accompanyingdrawings are referred to as forming a part of thisspecification, in which Figure l is a perspective View of the invention.Fig. 2 is a plan View, seat removed. Fig. 3 is an enlarged section alongline X X, Fig. 2, shafts omitted. of draw-bar rope-sheave. Fig. 5 is asection through part of axle, showing manner of fastening spindles andrake-head lock-pin hole. Fig. 6 is a detail showing spring-bar rakeheadlock and manner of fastening the same to frame and locking therake-head. Fig. 7 is a detail showing manner of coupling the tubularframe to axle. Fig. 8 is a section through the axle, showing the mannerof securing the enlarged rake-tooth seat to the axle and the springrake-tooth to the enlarged seat. Fig. 9 is a section through the axle,showing ratchet rope-sheave andspring-dogs or pawls locking therake-head. Fig. 10 is a section through Y Y, Fig. 9.

The revolving tubular axle 2 (see Fig. 5) is shrunken and riveted on thespindles 23. The running wheels are loosely mounted on the spindles 23.The ratchet rope-sheave 3 (see Figs. 1, 2, 3, and 9) is fitted looselyon ,to rotate backward thereon.

Fig. 4 is an end View I the center of the tubular axle 2 and adapted Thesmall ends of the pawls or spring-dogs 4 are secured .looselyto the sideof the ratchet rope-sheave 3, and the large ends of the spring-dogs 4engage the offsets countersunk in the opposite sides of the tubular axle2. The pawls or spring-dogs 4 rotate the axle 2 forward when dumping therake; but they ratchet backward on the axle 2 when the mechanism of therake is reset.

The enlarged rake-tooth seat 19 (see Figs. 1, 2, and 8) are secureddetachably to the re volving axle 2. The spring rake-teeth 22 aresecured detachably to the enlarged rake-tooth seat 19, both beingsecured to place by the clamping-bolt 21. The spring rake-teeth 22 areadapted to bear on the ground and rotate with the axle 2 alternately.The shank of the rake-tooth 22 is curved upon the same circle as theenlarged rake-tooth seat 19. The clip 31 confines the rake-tooth shankat that point. The upper ends of the spring rake-teeth 22 are providedwith an eye through which clamping-bolt 21 passes. The hay-fingers 33are fastened 'to axle-rings 18 and clean the load from the springrake-teeth 22 when the rake-head is rotated. The revolving axle 2 andthe enlarged rake-teeth seats 19 form the rake-head.

A tubular or pipe frame 15, (see Figs. 1, 2, 3, at, and 6,) providedwith shafts, is connected to the tubular axle 2 by means of theaxle-rings 18, (see Figs. 1, 2, and 7,) within which the axle 2 rotateswhen the rake is dumped. The sliding sleeves 26 are fitted loosely onthe shafts, the shaft carrying straps of the harness, and the safetybelly-band straps are secured to the sliding sleeves 26. The sleevesslide forward when the rake is dumped and slide backward when thedumping mechanism of the rake is reset.

and the draft of the horse.

from leaf-spring 9 also instantly rotates the 655 rope-sheave '3backward, automatically reteeth to the ground when raking. The spring ofthe bar rake-head lock 17 adapts it to be lowered at will. Such movementunlocks the rake-head and allows the rake-head and the rake-teeth to berevolved and dump the load from the rake-teeth.

The draw-bar rope-sheave 7 (see Figs. 1, 2, 3, and 4c) is fitted looselyupon the front center of the pipe-frame 15 and adapted to rotatebackward to dump the load from the raketeeth, and then instantly rotateforward and reset the dumping mechanism to its original position. rope)passes one and one-half times around rope-sheave 7, and thence back toand two and two-thirds times around the ratchet ropesheave 3, formingthe pull-rope 5, the ends thereof being clamped by rope-clamp 6,tightening the rope on the sheaves. The function of the pull-rope 5 isto revolve the rake-head forward and dump the load and rotate theratchet rope-sheave 3 backward and reset the pawls or spring-dogs 4after dumping.

The center of the leaf-spring 9 is rigidly secured to the pipe-frame 15.(See Figs. 1, 2, and 3.) The front end of the leaf-spring 9 is above andthe rear end below the leafspring pins 11 in draw-bar rope-sheave 7.When the rake is dumped, the leafspring pins 11 put strong tension onthe leaf-spring 9. (See dotted lines, Fig. 3.) The rebound from thetension on the leaf-sprin g 9 automatically resets the dumping mechanismof the rake.

The foot-lever l6 and the draw-bar and hook 8 (see Figs. 1 and 3) arerigidly secured to the draw-bar rope-sheave 7. Their functions arehereinafter described. The seat 29 is rigidly secured to the pipe-frame15 to the left'of the front center of the frame.

When the rake-teeth have gathered a load, the driver, occupying the seat20, taps downward with his left foot upon spring-bar rakehead lock 17,thereby disengaging lock-pin 28 from the axle 2, when the draft from thehorse quickly pulls draw-bar hook 8 forward and upward to thedead-center, when the pull there by applied to pull-rope 5 rapidlyrevolves the rake-head and the rake-teeth two-thirds way around anddumps the load from the raketeeth. The rapid rotating motion that therake-head and the rake-teeth has thus attained completes the revolutionof the rake-head and the lock-pin 28 automatically relocks therake-head, thereby locking the rake-teeth to the ground to gather thenext load. When the rake-teeth 22 are completing the latter two-thirdsof their revolution, the rake is empty, and a few pounds pull will thenmove the running wheels quickly forward clear of thewindrow, whichmovementis attained from the rebound from the tension on leaf-spring 9The rebound draw-bar rope-sheave 7 forward, the ratchet A small rope(preferably a wire storing the rope-sheaves 3 and 7, the springdogs 4,the foot-lever 16, the draw-bar hook 8, and the sliding sleeves 26 totheir original positions simultaneously.

In case of unforeseen accidents breaking the leaf-spring 9 the driverpresses forward on the foot-lever 16 with his right foot, manuallyresetting the dumping mechanism of the rake to its original position.

hen hauling the rake fromfield to field, on the road, or acrossirrigation-ditches, the rake is locked by an idle hook, holding therake-teeth up under the seat 29.

The rake can be operated with equal efficiency by attaching a guidetongue or pole with braces to the pipe-frame 15 and a donbletree to thedraw-bar hook 8.

I desire it to be understood that I do not propose in all cases torestrict my invention by attachment of a foot-lever to the draw-barrope-sheave, since advantageous results may be attained by havingfoot-pins on the side of the draw-bar rope-sheave and dispense withfoot-lever 16. Neither do I propose in all cases to restrict myinvention to the use of a pull-rope and a rope-sheave, sinceadvantageous results maybe attained by using a sprocket chain or belt.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a snlky hay-rake, the combination with a revoluble axle, andrake-teeth secured thereto, of a wheel loosely mounted on said axle forbackward rotation and provided with spring-dogs adapted to positivelyengage and turn the axle when said wheel is turned forwardly, and meansfor turning said wheel in both directions.

2. In a sulky hay-rake, the combination with a revolving rake, of anindependent rotatably or rockably mounted member operatively connectedwith the rake, releasable locking mechanism for the rake, and aconnection between the member and the draft apparatus, whereby the rakeis turned or revolved by the draft when said locking mech anism isreleased.

3, In a sulky hay-rake, the combination with a revolving rake, of awheel operatively connected with the rake, draft apparatus, a connectionbetween the draft apparatus and the wheel, and locking mechanism fornormally maintaining the point of attachment of said connection to thewheel at a point ofiset from that which it would normally assume, thatis to say, the dead-center of the wheel, whereby when the lockingmechanism is released the draft will turn the wheel and revolve therake.

4. In a sulky hay-rake, the combination with a revolving rake, of anindependent rotatably or rockably mounted member, an operativeconnection between the member and the rake, releasable locking mechanism,draft apparatus, a connection between the draft apparatus and themember, whereby the rake is turned or revolved when released, and aspring coacting with the member to cushion or elastically receive theshock of its sudden movement when released, which is also adapted toautomatically return the member to normal position after the load hasbeen dumped.

5. In a sulky hay-rake, the combination with a revolving axle, andrake-teeth secured thereto, of a ratchet rope -sheave loosely mountedfor backward rotation on said axle and provided with spring-dogs adaptedto positively engage with the axle on the forward rotation of saidsheave, a draw-bar ropesheave, a rope connecting the said sheavestogether, draft apparatus, a connection between the draft apparatus andthe draw-bar ropesheave,locking mechanism for normally maintaining thepoint of attachment of said connection at a point offset from that whichit would normally assume, that is to say, the dead-center of the sheave,whereby when the locking mechanism is released the draft will turn thesheave and revolve the rake, and a leaf-spring having its center portionsecured and its ends free and positioned for engagement by the draw-barrope-sheave,said spring being adapted to cushion or elastically receivethe shock of the sudden movement of said draw-bar rope-sheave andserving to return the same to normal position after the load has beendumped and also to turn the ratchet rope-sheave back idly on the axle tocause the dogs to assume their normal posi tion.

6. In a sulky hay-rake, the combination with a revolving rake, of anindependent ro' tatably or rockably mounted member, an operativeconnection between the member and the rake, releasable lockingmechanism, draft apparatus, a connection between the draft apparatus andthe member whereby the rake is turned or revolved when released, aspring coacting with the member to cushion or elastically receive theshock of its sudden movement when released, which is also adapted toautomatically return the member to normal position after the load hasbeen dumped, and a lever secured to said member and in convenientposition for manipulating by the driver, whereby the rake can be resetmanually.

7. In a sulky hay-rake, the combination with a revolving rake, of anindependent rotatably or rockably mounted member, an op erativeconnection between the member and the rake, releasable lockingmechanism, draft apparatus, a connection between the draft apparatus andthe member whereby the rake is turned or revolved when released, and alever secured to said member and in convenient position for manipulatingby the driver, whereby the rake can be reset manually.
